Making process of superfine denier modal fiber compact siro spinning knitting yarn

Abstract

The invention discloses a fine denier fiber compact siro spinning knitting yarn and a making process thereof. The making process of the yarn comprises the steps that 0.8 dtex*34 mm superfine denier fibers are separately subjected to a blowing procedure, carding of a cotton carding procedure, finishing of a drawing procedure and a roving procedure to be prepared into roving slivers with suitable weight and moderate twist degree, two kinds of rovings are fed into a spun yarn rear area double-horn opening during spinning in sequence, a compact siro spinning knitting yarn is made through high-multiple drafting, a suitable twist degree design and the use of other process special pieces, partial defect yarns and single yarns are cleaned away through a spooling procedure, the superfine denier modal fiber 120-count compact siro spinning knitting yarn is made, and the relative humidity of the environment of all procedures is 56-60%. The yarn and the process have the advantages that the made yarn has a compact structure, little hairness, good yarn slivers and moderate strength, the produced yarn can be made into various high-end textile underwear fabrics, and a super-comfortable textile product is added for the field of textiles.

Description

technical field [0001] The invention belongs to the technical field of spinning processing, and in particular relates to a manufacturing process of superfine denier modal fiber compact siro spinning knitting yarn. Background technique [0002] Due to the fineness of ultra-fine denier modal fibers, low breaking strength and poor fiber cohesion, they are easy to tear and slippery during the spinning process. Traditional spinning equipment is used to produce yarns with poor evenness and low strength. There are many hairiness and many defects on the cloth surface, so it is not suitable for making high-end knitwear. The production practice proves that the fine-denier modal fiber is spun into compact siro knitting yarn, which has evenness and moderate strength, and can meet the needs of high-grade knitted fabrics. [0003] Ultrafine denier modal fiber is a cellulose fiber raw material that is thinner and softer than ordinary modal. It is used to produce more high-end knitted fabr...

Problems solved by technology

However, due to the fineness of ultra-fine denier fibers (fiber specification 0.8dtex*34mm) and poor smooth cohesion of fibers, it is necessary to comb lightly and slowly in the cleaning process to reduce the generation of neps and short fibers and reduce hairiness; in the roving process It is required that the weight of the roving should not be too light, otherwise it will be easily broken or cannot be drawn;
